Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
Gaia Collaboration, P. Panuzzo, T. Mazeh +412
Gravitational waves from black-hole merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected base…
Gaia Focused Product Release: Spatial distribution of two diffuse interstellar bands
Gaia Collaboration, M. Schultheis, H. Zhao +15
Diffuse interstellar bands (DIBs) are absorption features seen in optical and infrared spectra of stars that are probably caused by large and complex molecules in the ISM. Here we…
Gaia Focused Product Release: A catalogue of sources around quasars to search for strongly lensed quasars
Gaia Collaboration, A. Krone-Martins, C. Ducourant +398
Context. Strongly lensed quasars are fundamental sources for cosmology. The Gaia space mission covers the entire sky with the unprecedented resolution of " in the optical, ma…
The cerium content of the Milky Way as revealed by Gaia DR3 GSP-Spec abundances
G. Contursi, P. de Laverny, A. Recio-Blanco +12
The recent Gaia Third Data Release contains a homogeneous analysis of millions of high-quality Radial Velocity Spectrometer (RVS) stellar spectra by the GSP-Spec module. This led t…
Gaia DR3: Apsis III -- Non-stellar content and source classification
L. Delchambre, C. A. L. Bailer-Jones, I. Bellas-Velidis +78
Context. As part of the third Gaia data release, we present the contributions of the non-stellar and classification modules from the eighth coordination unit (CU8) of the Data Proc…
Stellar ages, masses, extinctions and orbital parameters based on spectroscopic parameters of Gaia DR3
G. Kordopatis, M. Schultheis, P. J. McMillan +13
Gaia DR3 provides radial velocities for 33 million stars and spectroscopically derived atmospheric parameters for more than five million targets. When combined with the astrometric…
Gaia Data Release 3: Astrophysical parameters inference system (Apsis) I -- methods and content overview
O. L. Creevey, R. Sordo, F. Pailler +86
Gaia Data Release 3 contains a wealth of new data products for the community. Astrophysical parameters are a major component of this release. They were produced by the Astrophysica…
Gaia Data Release 3: Analysis of RVS spectra using the General Stellar Parametriser from spectroscopy
A. Recio-Blanco, P. de Laverny, P. A. Palicio +77
The chemo-physical parametrisation of stellar spectra is essential for understanding the nature and evolution of stars and of Galactic stellar populations. Gaia DR3 contains the pa…
Gaia Data Release 3: Exploring and mapping the diffuse interstellar band at 862 nm
Gaia collaboration, M. Schultheis, H. Zhao +12
Diffuse interstellar bands (DIBs) are common interstellar absorption features in spectroscopic observations but their origins remain unclear. DIBs play an important role in the lif…
Solid confirmation of the broad DIB around 864.8 nm using stacked Gaia-RVS spectra
H. Zhao, M. Schultheis, T. Zwitter +26
Studies of the correlation between different diffuse interstellar bands (DIBs) are important for exploring their origins. However, the Gaia-RVS spectral window between 846 and 870…
Gaia Early Data Release 3: Structure and properties of the Magellanic Clouds
Gaia Collaboration, X. Luri, L. Chemin +417
We compare the Gaia DR2 and Gaia EDR3 performances in the study of the Magellanic Clouds and show the clear improvements in precision and accuracy in the new release. We also show…
Gaia Early Data Release 3: Acceleration of the solar system from Gaia astrometry
Gaia Collaboration, S. A. Klioner, F. Mignard +414
Context. Gaia Early Data Release 3 (Gaia EDR3) provides accurate astrometry for about 1.6 million compact (QSO-like) extragalactic sources, 1.2 million of which have the best-quali…
